Python_Program

Scripting in PowerFactory with Python Python is a powerful tool, which is integrated into the standard PowerFactory application. It is commonly used to automate the execution of time-consuming simulations, but its application extends far beyond that. It may be used to process results, or to implement a routine that applies sequential changes to the network and calls PowerFactory’s analysis functions in each step. This seminar provides a compact and efficient introduction to the fundamental aspects of writing a scripts inside of PowerFactory by using Python. The course includes basic concepts, syntax, accessing and modification of objects from within the code, automation of a series of calculations and presentation of the results etc. Participants will be provided with numerous examples of Python scripts, which they may use for ideas, or adapt to suit their particular requirements. The number of participants is limited to 10. Each participant will have access to a workstation which will be used for the completion of exercises. Each participant should be familiar with the general handling of the PowerFactory software, acquired through our load flow and short circuit seminar, a PowerFactory basic training course or through relevant experience in the use of PowerFactory. Programming experience is a prerequisite.
